A semiconductor device has an on-die decoupling capacitor that is shared between alternative high-speed interfaces. A capacitance pad is connected to the decoupling capacitor and internal connection pads are connected respectively to the alternative interfaces. Internal connection bond wires connect the decoupling capacitor to the selected interface through the capacitance pad and the internal connection pads in the same process as connecting the die to external electrical contacts of the device.

Integrated circuit with on-die decoupling capacitors

A semiconductor device includes a semiconductor die having opposing first and second main surfaces, contact pads and a metal ring accessible from the first main surface, and signal leads surrounding and spaced from the die. Each of the signal leads has a first end near the die, a second end remote from the die, and a body extending between the first and second ends. A dummy lead frame is disposed between the signal leads first ends and the die, and connected to a fixed potential. First bond wires are coupled to respective ones of the signal leads and the contact pads. Second, shield bond wires, located adjacent to respective ones of the bond wires, are coupled to the dummy lead frame and the metal ring.

Signal bond wire shield

A semiconductor device has a multi-wire lead and a die having a multi-site bond pad. A shielding wire and a guarded wire both extend from the multi-wire lead to the multi-site bond pad. The shielding wire (or wires) provide active shielding to the guarded wire by simultaneously transmitting the same signal as the guarded wire between the multi-wire lead the multi-site bond pad.

Semiconductor device with active shielding of leads

A shielding structure for use with semiconductor devices. The shielding structure has a base with fingers that are sized and shaped to extend within the space between pairs of adjacent leads. The base extends within the space between the die flag and the leads. The shielding structure is further connected to one of the grounded leads.
